Effect of Refractive Solid Immersion Lens parameters on the enhancement of laser induced fault localization techniques

The effect of Refractive Solid Immersion Lens (RSIL) parameters on the enhancement to laser induced fault localization techniques are investigated. The experimental results of the effect on a common laser induced technique, namely Thermally Induced Voltage Alteration (TIVA), and imaging are presented. A signal enhancement in the peak TIVA signal of close to 12 times has been achieved.
